ABSTRACT:
A process for preparing a layered composition has been developed. The composition comprises an inner core and an outer layer comprising a molecular sieve. The process involves providing a slurry comprising inner core particles and sources of the framework elements of the molecular sieve. To this slurry there are added nutrient(s), i.e. framework element sources thereby forming crystals of the molecular sieve which agglomerate onto the inner core. The process is carried out for a time sufficient to form a layer of desired thickness.
